Moisture behind coating
Leaks, penetrations, sprinklers, plumbing, and trapped water can create pressure behind paint.
Chalk creates a weak bond
Old acrylic can break down to powder. New paint may bond to the powder instead of the wall.
Patches behave differently
Repairs can have different porosity, texture, and cure needs and may require spot primer.
Incompatible layers fail
Unknown old coatings, sealers, and glossy patches may need testing, abrasion, or primer.
Repair before color
The estimate should identify what is removed, repaired, primed, and coated.

General guidance cannot diagnose hidden moisture, unknown coatings, structural cracks, or access. A project estimate should be based on actual conditions.
